Good idea to try disabling Norton.
There's been a lot of similar problems posted here, it's not always what it seems though. There can be an interaction between Graphics, Network adapter and the audio card which causes sound to stutter. It can also be the odd background process that's causing a problem. It's also possible a BIOS update could help sort out conflicts.
I don't know if you have any slots left open but the first thing I would do is try moving the Audio card to a different slot.
Also quitting background processes related to ATI, plus any non system process that seems to be using an exorbitant amount of CPU.
If you type msconfig at either a command prompt or Start/RUN you can get an idea of what's being run at startup, also look in the startup folder.

p.s. Springfield eh? My grandfather used to paint the Capitol dome there, I was born in nearby Jacksonville. Haven't been there in many, many years.
